REFRIGERATING DEVICE FOR BOX-CARS.

SPECIFICATION' forming part of Letters Patent No. 416,285, dated December 3, 1889.

Application filed February 19, 1889. Serial No. 300,411. (No model.)

To all whom, it may concern:

Be it known that I, WILLIAM J. ARNOLD, of Kansas City,Vyzt11tlotte county, Kansas, have invented certain new and useful Improvements in Refrigerator-Cars, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming a part hereof.

This invention relates to improvements in refrigerator-cars; and it consists in a certain novel construction and arrangement of devices, as fully described hereinafter in connection with the accompanying drawings, and specifically pointed out in the claims.

In the drawings, Figure l is a sectional end elevation of a railroad-car embodying'my invention. Fig. 2 is a part longitudinal section Fig. 3 tive view of a cleat or strip interposed between each ice tank or receptacle and the car or inclosure, and Fig. 4 is a similar view of a bracket, a number of which are used in supporting the ice tanks or receptacles.

In carrying out my invention I employ an ice tank or receptacle B, or a number of the same, according to the requirements of the case, in the present instance four tanks or receptacles being provided in acar of ordinary size. The tank or receptacle B is or may be rectangular or cylindrical or other shape in cross-section, but gradually flares or increases in size downward, thus being larger at the bottom than a'J the top, whereby it is obvious the ice placed therein will by gravity continuously settle toward and always rest upon the bottom of the tank or receptacle as it reduces or lessens in bulk from melting. The advantage of this is that the salt pickle or brine in the bottom of the tank or receptacle will always be in contact with the ice and be kept at a freezing-temperature, thus preventing the salt pickle from becoming warm, which would result in rising temperature. This latter is a disadvantage that often arises or happens in the use of ice tanks or receptacles having a uniformity of cross-section, owing to the clogging or wedging together of the ice, which holds it away from the salt pickle or brine, resulting, as above intimated, in its becoming warm and in rising temperature, the consequence of which is the contents of the car are injured. These tanks are supported is a detached perspec-v in position by means of brackets C C', bolted through their vertical portion at f f to the end of the car, and angle-irons or approXimately L shaped castings G, fastened or bolted to the sides of said tanks and resting upon said brackets. The brackets C C are each of a proximate inverted-L shape, and have a short foot g, which is fastened to the floor of the car, and they (the brackets) are preferably T-shaped in cross-section in their vertical portions, and have in their horizontal portions or arms at a suitable distance apart perforated or apertured flanges Gr. Through apertures in said flanges G and apertures in the horizontal portions or arms of the angleirons or castings G are inserted bolts fastening the same together.

The brackets C are relieved of a portion of 'their strainby the diagonal brace-rods D,

passed through the outer ends of their horizontal arms and nutted below the'latt-er and extended up to and looped, as at b', upon pendent screw-hooks ZJ, screwed into the upper edge of the car-body. The end brackets C', however, have no brace-rods applied to them, none being needed there.

The tanks or receptacles B are isolated or separated from the car by scalloped or serially-notched bars or strips E, to permit of the circulation of air-currents behind said tanks or between the same and the car, the

air passing through the notches aforesaid. The tanks are provided with downwardlycurved or dished bottoms, having their lowest point at the center in order to cause the sawdust, dirt, dac., to collect at that point, whereby it may be readily removed, and plugged openings h in the sides of the tanks or receptacles B permit of the clearing of the same when desired. These tanks or receptacles are also -provided with overflow-pipes H, discharging into pans F below, from which the water passes through the outlets d in the bottom of the car.

The openings inthe top or roof of the car, through which the tanks or receptacles are supplied with ice, may be provided with rounded or flat trap-doors CL, which are preferably hinged attheir inner edges to the roof of thecar, and are engaged at their outer edges by suitable buttons K along the lower edge of the roof.

IOO

The tanks are preferably arranged in pairs, as shown in Fig. l, with their adjacent walls b2 b2 connected by a rounded portion or projection b3. The outer or remote sides of each pair of tanks are extended upward and flared outwardly to iit in the openings in the roof of the car, and caps or lids a are fitted in the tlared mouths of the tanks and bear at their centers on the rounded portions b3, which connect the adjacent walls of the tanks, thereby separating or cutting off all communication between the tanks. It will be seen that this inode of connecting the tops of the tanks to the car causes a portion of the weight of the former to be supported by the roof ol? the ear, and also enables a perfectly air-tight joint to be ell'ected between the walls of the tanks and the cap or lid. The caps or lids may be secured in place in any ordinary or preferred manner, and the under sides of the trap-doors a a are recessed, as at a2, to provide an airspace above said caps or lids, which acts as a non-conductor of heat.

The peculiar manner of supporting the tanks by means oi' angle-irons G, attached to its side walls and resting on brackets, leaves the lower ends ol' the tanks freely suspended and out of contact with all wood-work and iron-work, thereby pcrmittin the ready cleaning of the drip-pans of all impurities or sediment, and preventing the circulation of iinpure air which would arise in the presence of saturated wood-work. ble to occur from the dripping or overiiow water, thereby producing' a sour and moldy atmosphere, the etlect of which, it is obvious, is to injure the contents of the car. A further advantage of this peculiar manner of supporting' the tanks in position is, that their entire surfaces are exposed to the currents of air within the car, thereby increasing the effectiveness of the tanks, and producing a lower temperature with the same consumption of refrigerating material.

It will be understood that my tank or receptacle can be applied or used in storage-refrigerators in meat stores and elsewhere.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, 1s-

Such saturation is lial. In a refrigerator car, the tanks arranged in pairs,with their adjacent Walls connected by an integral rounded portion or projection and having their outer walls iiared outwardly to lit in flared openings in the roof ot' the car, and the caps or lids tting in the flared mouths of the tanks and bearing at their centers on the intermediate rounded portion or projection between adjoining tanks, substantially as specified.

2. In a refrigerator-car, the combination, with the supperting-brackets C, attached to the sides of the car, the horizontal arms thereof having apertured flanges G', of the tanks B, having heinispherical or semi-cylindrical bottoms and suspended between the brackets C by means of the angle-irons G on their sides, whereby the lower parts of the tanks are below the horizontal arms oi' the brackets and in front of their vertical arms, giving ready access to the tank-bottom, sub stantially as described.

3. In a refrigerator-car, the combination, with the brackets C, provided with horizontal apertured arms and having horizontal feet g resting on the floor of the car, of the tanks arranged .at their lower ends between the horizontal arms of the brackets and provided at their sides with angle-irons which rest on said horizontal arms and are bolted thereto, substantially as specilied.

4. In a refrigerator-car, the combination of brackets arranged at intervals and having parallel horizontal arms, the tanks arranged at their lower ends between said horizontal arms and provided above their lower ends with side projections bearing on the brackets, and the brace rods arranged between the tanks, connected at their upper ends to the car and at their lower ends to the free ends of the horizontal arms of the brackets, substantially as specified.

In testimony whereof I affix my signature in presence of two Witnesses.

WILLIAM J. ARNOLD.
